Nursing Elites

1. A client with a diagnosis of rheumatoid arthritis is prescribed methotrexate. What is the primary action of this medication?

• A. Increases joint lubrication
• B. Reduces inflammation by suppressing the immune system
• C. Enhances bone density
• D. Stimulates cartilage regeneration

Correct answer: B

Rationale: The correct answer is B: Methotrexate is an immunosuppressant that works by suppressing the immune system, thereby reducing inflammation in rheumatoid arthritis. Methotrexate does not directly increase joint lubrication (Choice A) as its primary action is on the immune system. Choices C and D are incorrect since methotrexate does not enhance bone density or stimulate cartilage regeneration. It is crucial for healthcare providers to understand the mechanism of action of medications to provide safe and effective care to patients.

2. A client is prescribed warfarin for the prevention of thromboembolism. What dietary instruction should the nurse provide?

• A. Increase intake of green leafy vegetables
• B. Maintain a consistent intake of vitamin K-rich foods
• C. Avoid all foods containing vitamin K
• D. Consume a high-protein diet

Correct answer: B

Rationale: The correct answer is B. Maintaining a consistent intake of vitamin K-rich foods is important for patients taking warfarin as it helps keep the effects of the medication stable. Choice A is incorrect because while green leafy vegetables are high in vitamin K, they should not be avoided completely but rather consumed consistently. Choice C is also incorrect as avoiding all foods containing vitamin K can lead to fluctuations in warfarin's effectiveness. Choice D is incorrect as a high-protein diet is not specifically recommended for patients taking warfarin.

3. When caring for a client with a urinary catheter, what is the most important intervention to prevent infection?

• A. Use sterile technique for catheter care
• B. Ensure the catheter bag is below the level of the bladder
• C. Provide perineal care daily
• D. Change the catheter only when necessary

Correct answer: B

Rationale: The most important intervention to prevent infection when caring for a client with a urinary catheter is to ensure that the catheter bag is below the level of the bladder. This positioning helps prevent urine backflow, reducing the risk of infection. While using sterile technique for catheter care (Choice A) is important, ensuring proper drainage by keeping the catheter bag below the bladder is crucial to prevent infection. Providing perineal care daily (Choice C) is essential for hygiene but not directly related to preventing catheter-related infections. Changing the catheter only when necessary (Choice D) is important for maintenance, but correct positioning of the catheter bag is more critical in preventing immediate infection.

4. Before administration of a stat dose of potassium chloride IV for a client with hypokalemia, what is the most important action for the nurse?

• A. Ensure the IV is flowing freely
• B. Mix the medication thoroughly
• C. Check the client’s electrolyte levels
• D. Obtain a baseline ECG

Correct answer: A

Rationale: The most crucial action for the nurse before administering a stat dose of potassium chloride IV to a client with hypokalemia is to ensure the IV is flowing freely. A freely flowing IV is essential to safely and effectively deliver potassium chloride, helping to prevent infusion-related issues. Checking the client's electrolyte levels or obtaining a baseline ECG may be important but are not the most critical actions before administering the medication. Mixing the medication thoroughly is not applicable in this scenario as potassium chloride is typically provided ready to use.

5. What is the most important action to prevent catheter-associated urinary tract infections (CAUTIs) in a client with an indwelling urinary catheter?

• A. Irrigate the catheter daily.
• B. Change the catheter every 72 hours.
• C. Apply antibiotic ointment at the insertion site.
• D. Ensure the catheter bag is always below bladder level.

Correct answer: D

Rationale: The most crucial action to prevent catheter-associated urinary tract infections (CAUTIs) in a client with an indwelling urinary catheter is to ensure that the catheter bag is always below bladder level. This positioning helps prevent backflow of urine, reducing the risk of CAUTIs. Irrigating the catheter daily (Choice A) is unnecessary and can introduce pathogens. Changing the catheter every 72 hours (Choice B) is not recommended unless clinically indicated to prevent introducing new pathogens. Applying antibiotic ointment at the insertion site (Choice C) is not the most important action to prevent CAUTIs; proper hygiene and maintaining a closed system are more critical.
